How to Fix CVE-2021-21677

To remediate this vulnerability, upgrade all affected Code coverage api dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

io.jenkins.plugins:code-coverage-api fixed: 1.4.1 
<dependency>
    <groupId>io.jenkins.plugins</groupId>
    <artifactId>code-coverage-api</artifactId>
    <version>1.4.1</version>
</dependency>
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

mvn dependency:tree -Dincludes=io.jenkins.plugins

How to Check if You Are Affected

To determine whether your Java application is affected by CVE-2021-21677, inspect your build dependencies using the Maven Dependency Plugin:

mvn dependency:tree -Dincludes=io.jenkins.plugins

Analyze the terminal output to locate any version of Code coverage api in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 1.4.1), your application is affected.

Note: The mvn dependency:tree -Dincludes=io.jenkins.plugins command inspects the resolved dependency graph declared in your project's POM files; it does not perform automated security scanning or inspect runtime dynamic classpaths. Always verify runtime container classpaths and shaded JARs.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-502: Deserialization of Untrusted Data, where the product deserializes untrusted data without sufficiently ensuring that the resulting data will be valid. In Code coverage api, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

Jenkins Code Coverage API Plugin 1.4.0 and earlier does not apply [JEP-200 deserialization protection](https://github.com/jenkinsci/jep/tree/master/jep/200) to Java objects it deserializes from disk. This results in a remote code execution (RCE) vulnerability exploitable by attackers able to control agent processes. Jenkins Code Coverage API Plugin 1.4.1 configures its Java object deserialization to only deserialize safe types.
